If the plane to the coils are perpendicular to the field which of the following statements is true? An emf is induced in split coil. Joule heating does not occur in each of the coils. An emf is induced in both coils. Equal joule heating occurs in both coils. An emf is induced in split coil. Joule heating does not occur in each of the coils. An emf is induced in both coils. Equal joule heating occurs in both coils. ANSWER DOWNLOAD EXAMIANS APP
Electromagnetic Field Theory A rectangular loop in the x – z plane bounded by the lines x = 0, x = a, z = 0 and z = b is in a time varying magnetic field is given by B = B0 cosωt + ay. Where B0 is constant, ω is angular frequency and ay unit vector in the y direction. Now the emf induced in the loop is given by abω Bo sinω t. Bo ω sinω t. ab Bo cosω t. Zero. abω Bo sinω t. Bo ω sinω t. ab Bo cosω t. Zero. ANSWER DOWNLOAD EXAMIANS APP
